Although the field of polarity is well researched, this monograph offers a new
take on polarity sensitivity that both challenges and incorporates previous
theories. Based primarily on Swedish data, it presents new solutions to long-
standing problems, such as the non-complementary distribution of NPIs and
PPIs in yes/no-questions and conditionals, long distance licensing by
superordinate elements, and the occurrence of polarity items in "wh"- questions.
It is argued that polarity sensitivity can be understood in terms of "evaluability".
Lacking any immediate predecessor in the literature, evaluability refers to the
possibility of accepting or rejecting an utterance as true in a communicative
exchange. Intriguingly, the evaluable status of a clause is shown to have
syntactic correlates in Swedish, mirrored in the configuration of the C-domain.
This book is of interest to scholars studying the interplay between syntax,
semantics and pragmatics, particularly those working on negation and polarity.
